I no longer have Toast 7 on any computer. One thing that can prevent Toast from launching is the presence of any Xvid codec in one of the Library>QuickTime folders. If you have any of these trash them and install perian instead.

I'm just a fellow Toast-user so please don't blame Roxio for any misguidance I may provide. And do let me know if your issue gets solved. Cheers from Eugene, Oregon!

I was having the same problems as the original poster on this thread -- Toast 7.1.3 just suddenly refused to open. The drive on my MacBook Pro would make its normal "access" sounds, and then the app would "unexpectedly quit".

I deleted the Xvid file that I had in my Library>Quicktime folder, emptied the trash, reopened Toast 7 and it worked.
